Abstract
Electrochemical measurements are increasingly being used to evaluate the durability of coatings and polymer films in significantly shorter times than those needed to complete long-term exposure tests. Electrochemical measurements have their limitations and nuances. Variability of data, collecting data before samples reach steady state, and misinterpretation of the data can lead to erroneous estimations of coating and polymer film durability. However, replicate samples, monitoring open circuit potential, and capacitance magnitudes can be used to develop more accurate estimations of polymer film, coating, or coated metal durability from electrochemical data.
